It is finally done, the Raspberry Pi (with no HDMI) portable MAME emulator based on the Raspberry Pi A+! Ben and Felix have put the finishing touches to the portable gaming device with the use of laser cutting and 3D printing. With 8 GPIO left though, Felix decides that it's best to do a low-level input for the buttons and directional pad to control the device.

    If Pi Zero W uses the Wifi/BT like the Pi 3 does (which is likely) then it's using the hardware UART for WiFi and pinning out a software UART to the GPIO. I've run Pi 3's with this LCD device tree overlay…

    Hi Joe, It is possible to get an audio output from the Pi Zero with an I2S Class D Amp and speaker. I have had success with this breakout from Adafruit https://www.adafruit.com/product/3006 It was used…

    This is very cool and I love that you provided the full plans.  Is there a particular reason you used the "A" model instead of a zero?  What about charging the battery?  Did you include a mechanism for that or was that beyond the scope?

    What is the matierial used for the laser-cut faceplate?  It looks very nice and the closest thing I could find is brushed aluminum plated acrylic sheets over at Inventables.

    Absolutely amazing work you both have done here and thank you for also including the parts used.

     

    If I wanted to do this using a RPi Zero W model, would the LCD still work? I'm not too worried with the amount of GPIO pins available (audio purposes) as I'd probably attempt to create a portable handheld instead (GB,GBC,GBA,Game Gear, Lynx, etc). Would there be any other drawbacks using a Zero vs. the A+?
